Trough is a narrow channel which forms the component of a roof. Its function is to collect and divert rain water from the roof. The main benefit of installing trough system is to protect a building’s foundation and channelize water away from its base so that the house doesn’t get damaged.
The structure helps in collecting rain water, reducing erosion and preventing leaks in basement and roofs. Check out here https://bprungruang.com/รางน้ำฝนกี่ประเภท/ for trough installation services in Thailand.

Rain troughs are made from various type materials such as iron, lead, zinc, galvanized steel, copper, painted aluminium, concrete, stone, wood and PVC etc. the structure may or may not be durable as per the material quality.
Water is collected through the downspouts which are placed from the roof edge to the base length where it discharges the water which is collected into a barrel or cistern.
Leakage, poor drainage, rust, sagging or hanging start small and grow bigger with time as the leaves, twigs and other debris collected during storm block the waterway and the water is accumulated on the roof.
Seasonal cleaning of guttering will not let the garbage accumulate and ensure the protection of house. Periodical cleaning will improve the trough life as well as maintain the cleanliness at home.
Installing leaf guards will ensure that the storm debris does not collect into the trough and avoid protection against blistering, flaking and peeling and leakage.
